Description

Sets up Jest testing infrastructure and initial tests for the Upup component library.

Changes

• Configured Jest and JSDOM test environment
• Added tests for:
  • MetaVersion component
  • checkFileType utility
  • s3GeneratePresignedUrl service
• Set up test coverage requirements (1% across all metrics until tests for prior features are added)

Test Setup

• Frontend: @testing-library/react
• Backend: Jest mocking for AWS services
• Essential mocks for Google and Framer Motion

Usage

pnpm test           # Run tests

Suggestions additional Test Cases:

Invalid s3ClientConfig: Test how the function behaves when provided with an invalid or incomplete s3ClientConfig.

it('should handle invalid s3ClientConfig', async () => {
    const invalidS3Config = { ...mockS3Config, region: '' } // Empty region
    await expect(
        s3GeneratePresignedUrl({
            fileParams: mockFileParams,
            bucketName: mockBucketName,
            s3ClientConfig: invalidS3Config,
            origin: mockOrigin,
            provider: mockProvider,
        })
    ).rejects.toThrow(UploadError)
})

Missing Parameters: Ensure the function properly handles cases where required parameters are missing.

it('should throw an error when required parameters are missing', async () => {
    await expect(
        s3GeneratePresignedUrl({
            fileParams: mockFileParams,
            bucketName: '',
            s3ClientConfig: mockS3Config,
            origin: mockOrigin,
            provider: mockProvider,
        })
    ).rejects.toThrow(UploadError)
})
